Digital logic is taught globally in almost all engineering schools. The subject consists of elementary knowledge of Boolean algebra, simple logic gates, and design of an elementary computer. With the help of AND, OR, and NOT, we can make any digital circuit. Recently, there has been increasing interest in the creation of deoxyribonucleic acid (DNA) logic gates due to forthcoming applications in the medical field. This article explains elementary ideas about AND, OR and NOT gates based on DNA-strand displacement. Once these gates are made, the path to developing any DNA digital circuit becomes open. DNA gates can be used for both DNA logic circuits and DNA computers. In this article, we provide the fundamentals of DNA circuits with possible applications.
